CPT code 37241: Venous embolization, nonhemorrhagic venous target2026 Medicare rate & RVUs

Medicare pays $4,393.22 for 37241 nationally in the office and $371.08 in a hospital or facility. Local office rates run $3,799.36–$6,202.00.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 37241 covers

Code 37241 reports catheter-directed closure or embolization of a vein for a nonhemorrhagic problem, such as a symptomatic varicocele, pelvic venous reflux, or a congenital or acquired venous malformation. An interventional radiologist or vascular specialist may deliver coils, plugs, or a sclerosant through a catheter under imaging in an angiography suite or another procedural setting. The target is venous; code selection does not depend on a particular embolic material.

Select this code by the treated venous condition; use the arterial, organ or tumor, or hemorrhage code when that is the treatment purpose. The embolization service includes the imaging guidance, roadmapping, and radiological supervision and interpretation needed to perform it. Document the target vein, indication, access and catheter work, embolic method, and completion findings. The 0-day global period includes same-day preoperative and postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Modifier 50 is inappropriate; Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery reporting are not permitted.
